Find Out More About Loft Conversions
Every CS Lofts project is designed by our in-house architect. At the start of your loft conversion project, we survey your South London property to understand the roof structure, available head height, access options and the amount of usable space that can be created.

Our goal is to help you understand what is possible before work begins, including the best conversion type, likely build process and any planning considerations.

What Types Of Loft Conversion Are Available?
There are several types of loft conversions available in South London, and the right choice depends on your roof shape, property type, planning restrictions and the amount of space you want to create.
Dormer loft conversions are one of the most popular options because they add usable floor space and head height by extending part of the existing roof.
Velux roof conversions are often suitable when the existing loft already has enough head height and the roof structure does not need major alteration.
Hip-to-gable loft conversions are commonly used on semi-detached or end-of-terrace homes with a sloping side roof, creating more internal space by extending the roof line.
Mansard loft conversions can create a large amount of additional space and are often considered for period properties or homes where a larger loft extension is required.
CS Lofts can assess your South London home and explain which loft conversion type is likely to work best.

Frequently Asked Questions
What types of loft conversions are available in South London?
The main types of loft conversions available in South London include dormer, Velux, mansard and hip-to-gable conversions. The best option depends on your property type, roof structure, head height, planning restrictions and the amount of space you want to create.
Dormer loft conversions are popular for adding head height and floor space. Velux conversions are usually less disruptive and work well where the existing loft already has suitable height. Hip-to-gable conversions are often suitable for semi-detached and end-of-terrace homes, while mansard conversions can create a larger loft extension, particularly on some period properties.
CS Lofts can survey your home and recommend the most practical option.
How long does a loft conversion take in South London?
A typical loft conversion in South London usually takes around 8 to 12 weeks, depending on the size and complexity of the project. Simpler Velux conversions may be quicker, while larger dormer, mansard or hip-to-gable loft extensions can take longer.
The timeline can also be affected by structural work, bathroom installation, bespoke joinery, planning permission, party wall matters and building regulation requirements. Before work begins, CS Lofts provides a clearer project timeline based on your specific property and chosen design.
Are loft conversions in South London a worthwhile investment?
Yes, loft conversions in South London are often a worthwhile investment because they add usable living space without reducing garden space or requiring a move. A well-designed loft conversion can create an extra bedroom, ensuite, home office or flexible living area, making the property more practical for everyday life.
In many South London areas, where space is valuable, a good loft extension can also make a home more appealing to future buyers. The exact value added depends on the property, location, quality of work and the type of loft conversion completed.
Do I need planning permission for a loft conversion in South London?
Many loft conversions in South London can be completed under permitted development rights, meaning full planning permission may not be required. However, this depends on the property type, roof changes, size of the extension and whether the home is in a conservation area or is listed.
Mansard loft conversions, flats, maisonettes and properties with previous extensions may be more likely to need planning permission. Loft extension planning in South London can vary by borough, so it is important to check the rules before work begins.
CS Lofts can assess your property and advise whether planning permission is likely to be needed.
Can CS Lofts handle complex loft conversions in South London?
Yes. CS Lofts can manage complex loft conversions in South London, including projects that involve structural alterations, unusual roof shapes, conservation area considerations, party wall matters or more detailed planning requirements.
Our team can advise on design, construction, building regulations and the practical steps needed to complete the project properly. Whether your property needs a mansard conversion, hip-to-gable extension, dormer addition or a more bespoke loft renovation, we can guide the process from survey to completion.
How does the process of a loft conversion with CS Lofts work in South London?
The process usually begins with an initial consultation and property survey. We assess your loft space, roof structure, head height and access options, then discuss how you want to use the new room.
After that, we prepare a design and quote based on the most suitable loft conversion type for your South London home. If planning permission, permitted development checks, party wall agreements or building regulation approval are needed, we help guide those stages.
Once everything is agreed, construction begins. Throughout the build, CS Lofts keeps you updated so you understand what is happening at each stage of the loft conversion.
